particulate matter monitor Applications

Sampling dust and particulate matter is important as dust and particulate matter can affect the health of human populations, as well as the natural environment. Dust and particulate matter can cause respiratory problems when breathed in by humans. Dust and particulates above 10 micrometer (PM10) are filtered and generally do not enter the lungs.

OPSIS provides real-time, flexible monitoring of particulate matter in the ambient air. Particulate matter monitoring with OPSIS, is a cost-effective solution, is ideally suited for use in modern monitoring stations. It can be remote controlled and includes automatic calibration, features that frees time. The SM200 meets the new regulation for automatic monitoring of PM10 and PM2.5. It also meets the new regulation for particulate matter sampling on filter membranes for further analysis of cadmium, nickel, PAH and other substances.

With the advent of specific process emission limits being defined, continuous particulate monitoring has become a regulatory requirement for many industries.
smoke stack #1Particulate monitoring requires the measurement of the mass concentration of particulate matter in stack emissions to atmosphere. There is no known method of continuously measuring particulate concentration by direct measurement and therefore, all continuous particulate measurement methods are inferential.
Each method involves the measurement of a parameter related to particulate concentration and then requires a calibration to be determined to convert the measured value into one of particulate mass concentration.

Ormantine offers a wide range of products and services to meet the array of different needs that arise in the oil and gas industries. Volatile Organic Compounds (VOCs), benzene, and other compounds are released during drilling, hydraulic fracturing (fracking) and other extraction procedures. Monitor NOx emissions from heavy duty equipment, particulate matter, and ground level ozone, the formation of which is contributed to by VOCs from processing, transportation, and storage of oil and gas.

Traffic means mobility and air emissions. Thanks to economical advantages, diesel engine becomes more and more popular, but particle emission is strictly restricted by regulations. Determining the weight of particulate matter (PM) is a key task in the automotive industry and one which is likely to become even more important as emissions standards become stricter. To allow fast and easy measurement of particulate matter at any time, METTLER TOLEDO has developed new filter weighing solutions.

In recent years, new regulations have been introduced governing emissions from ships. With the International Maritime Organization (IMO) adopting Annex VI of MARPOL designed to limit sulphur oxides (SOx), nitrous oxides (NOx) and particulate matter emissions, as well as introducing emission control areas (ECAs) to reduce emissions of those air pollutants further in designated sea areas, ship owners/operators can face hefty fines for failing to meet these new requirements on the “polluter pays” principle.

The exhaust gas from combustion engines is a complex mixture of gases and particulate matter. The composition of the gas may change rapidly. Multicomponent analysis of exhaust gases can be performed with a Gasmet™ FTIR Gas Analyzer with a response time (T90) of one second. The winning combination is the result using of a small volume gas sample cell, a powerful sample pump and a fast detector with liquid nitrogen cooling. The analyzer, sampling system and computer can be assembled on a cart for use in a dynamometer laboratory, or the portable version can be used for roadside tests.

Particulate matter, suspended particulate matter, atmospheric dust, particulate matter, total suspended particulate (TSP), are terms that commonly identify the group of substances suspended in the air (fibers, carbon particles, metals, silica, polluting liquid or solid). Particulate matter is the pollutant that is now considered the greatest impact in urban areas, and is composed of all those solid and liquid particles dispersed in the atmosphere, with a diameter ranging from a few nanometers to 500 microns and above (ie billionths of a meter to half a millimeter).

SedEvent is an event-driven, automatic grab sampling system that provides a simple and practical method of accurately determining suspended sediment and nutrient loads.
While suspended sediment concentration (SSC) cannot be directly measured accurately or reliably, turbidity has been shown to be an excellent surrogate for SSC. Turbidity is caused by suspended particulate matter such as clay, silt, algae, organic and inorganic chemicals and acids like fertilizers, and microscopic organisms like harmful bacteria. These contents give water its cloudy or turbid appearance, and turbidity in natural waters is recognized as an important indicator of natural health.
Measuring suspended sediment concentrations used to be labor-intensive, costly, inaccurate and impractical. SedEvent not only makes it possible and practical, it makes it simple.

It has been established that organic aerosol (OA) makes up for a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass.1,2
Primary OA is directly emitted in the troposphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic or anthropogenic gas-phase precursors and subsequent partitioning of the less volatile products into the particle phase.
The current number is that, on a global scale, SOA would represent around 60% of the overall OA.3 However, recent global mass-balance estimations for the removal of volatile organic compounds (VOC) suggest that this number could under-predicts SOA production.4 Recent field measurements in urban locations are also in support of a larger share, indicating that SOA is the dominant fraction of OA, with amounts considerably 20 greater than models predictions.
